To ad whom t may concern.'

Be it known that I, WALL/ion Il. HULL, a citizen of the United States, residing at Pittsl'iurgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful In'iprovemeixts in lllachines for Assembling Bolts and Nuts, of which the following is a specification.

This invention relates to a` nutting machine or o an apparalus or a mechanism for appliying nuts to bolts to prepare the latter for commercial vendition.

One object of the invention is to provide nierhanism for expeditiously and effectively feeding bolts and nuts into relatively en` gaging positions for positive assemblage, and to ultimately discharge the nutted bolts ready for packing for the t.rade. A still further ooject of the invention is to geucrally improve and sin'iplify the operation ol' this class of machines by providing them with novel means for causing a feeding action of the nuts and gravitating feeding action and accurate placement of the bolts over and in engagement with the nuts and a retention of thi` nuts against rotating while the bolts are individually rotated and uniformly screwed into the mits. A still further object of the invention is to entirely dispense with hand labor in thc assemblage of bolts and nuts by means of automatic l'nechanism controlling the feed of the bolts and nuts in regular sequence and in timed relation, and also to remove unused nuts or those which are not assembled with the bolts to avoid checking the operation of the machine and interference with the regular feed of the nuts from a source of supply.

Vith these and other objects and advan'- tagesin view, the invention consists inthe construction and,arrangement of the several parts which will be `more fully hereinafter described and claimed. i

The numeral 5 designates a` suitable base consisting of a frame striusture, that, may be of any form for the purpose of supporting the various parts, and embodying components in practical position for engagement by the various mechanical devices and cooperatingr elements comprised in the improved machine. As shown, this base consists of a lower frame (3 of metal or other material having` end uprights 7 connected to a-top frame 8 provided with a longitudinal member 9. The base, including the parts 4 just explained, will bc braced and supplied with any other structural features that' may be found necessary for conveniently a;se1nbling the several mechanical parts mi elements. ln a suitable position in the base and laftween the upper and lower frames (i andt, a vertically disposed drive shaft 10 is mounted and actuated from a suitable source, of power in a manner which will be presently sel forth. (ln this shaft 10 is a lower bevel gear Il with which a corresponding gear l2 on a power transmittingr shaft. t3 has engagement, said power shaft 13 runningr from a suitable source of power and may he equipped with the usual form of clutches for throwingr the salue into and out of operative connection With relation lo the source of power. )n the shaft l() is a bevel lLgvar 14 at :t .sllitahle distance :there the gent' ll, antl meshing' with the haitl geur 14 i=ta |v\vl gear t3 un the one vntl of a shaft' lt .svrring as a puwvr transntittiln' shaftV :intl

but suficient base support is provided at each side of the said slot 56 for the nuts. In other words, the slot 56 is of less width than the maximum transverse extent of the nuts. The free or outlet extremity 55 of the channel 54 stands above the carrier 34, but is deflected downwardly as at 57 to bring the free extremity or outlet in close relation to the upper edges of the flanges 45) or nut pockets. The flanges 4t) ot the nut pockets clear the downwardly detiectingr free extremity or outlet 55 of the channel, but the distance that the nuts move from the said outlet into the pocket is slight in order to insure regular disposition ot' the nuts in the successive pockets. The feedeiI for the nuts or the means for moving` the same into channel 5l consists of a disk 58 which is adjustable on the shaft 37 above the plane of the channel 5l and is provided with elongated arms or rods 5l) which sweep closely over the channel 54 and engage the nuts and push the latter fully around the channel.y the said arms or rods 59 having brush terminals U0, as clearly shown by Fig. 5, which extend .into the channel and engage the several nuts with a sweeping action. The nut feeder, comprisingr the disk 58 and the arms or rods 5l), is moved in timed relation to the carrier 34 by the pins l striking the arms or rods 47 of the actuator 45 and thereby give the interval rotation to the shaft 37. As the nuts are moved into the free extremity or outlet 55 of the channel 5l, the lingers 5U ot the several nut pockets enter tbe rear port ion of the slot 56 and engage the rear edges of the nuts and steadily guide the latter and cause them to regularly t'all or drop into the pockets, said fingers acting in conjunction with the brushes (5U of the arms or rods 5t) of the nut feeder. The fingers 50 also serve as back stops for the nut pockets and after the nuts have been fed into the pockets and move regularly around to the point of engagement with the bolts` they are l'orccd closely into the pocketsr by coming' into enlfrag-ement with a placement brush til carried by the lower angular extremity 62 of a vertical rod 63 secured toone side of the top frame 8, the rod 63 being bent at its lower extremity to properly dispose the brush lil beneath the lower member of the bolt feeder and placer above the nut carrier 34. In the event that`a nut passes around with the carrier and docs not become assembled with a bolt, it is displaced from its iocket by a nutl remover consisting of a roi 64 yieldingly secured lo a hanger 65, as shown by Fi". '2, and having a share (iti fixed thereon and operating lo throw the nut outwardly over the edge of the rotating carrier 34. The rodvl4 is held in the groove 52, being' suitably.

curved to t'olloilI in the groove. the said rod and thc Ishare operating as .-1 plow and by means olI this attaclnncnt thc pmfkets will outer end of thc 'angular member H4 ot' always come up and pass under the outlet or free extremity 55 of the channel 54 in condition to receive a nut and whereby the operation of the nut supply and feed is not; in the least checked.

The bolt feeder and placer 35 comprises upper and lower members (57 and G8, each member consistingr of a pair of thin sheet metal dis-lts 69 and 7U which are spaced apart and formed with outwardly projecting teeth 71` which have straight edges 72 slightly inclined into curved recesses or seats 73. Be tween the plates (il) and are pairs of antifrictional rollers or disks 7-l mounted on vertical shafts 75. the exposed adjacent to the seats 73. The shafts haveI bearin, r in the plates (SS) and 70 and` the rollers or disks 74 are' mounted thereon to loosely rotate so as to yn'event binding` rollers or disks 74 being--80 ot' thc bolts at the inner terminals of the 85 devices 76, which also 90 positively moved b v the teeth without liability of dis-` Y placement from vertical position.

'lhe bolts are t'ed into a hopper 77`which is shaped to cause the bolts to turn and fall through a central longitudinal slot 78 formed iu-thc hopper. rl'he hopper 77 tapers or com vere-es toward thc lower or inner outlet end 75l thereof, the slot 7h forming twb narrow sup iorting ledges Htl at the inner outlet end of t ze hopper. The hopper 77 is shownv in detail by Figs. 1l and 12 and is oscillated through the `medilnn of an arm or bar S1 connected to a pendant S1" of a band or volte S2 secured to the lower side of the hopper, the arm 81 being an elbow lever and fulcrumed, as at H25, to a hanger Sil" movably secured to a supportiln;r bar HIS" attached to the frame and the hopper., as shown. the lower tbc said arm extending in the path of movement of the arms or rods -ltl of the upper bolt lnovcr ill), and havin.;r a spring;r H5 attached thereto to return it to normal position, the opposite end of this s )ring heine' secured to un adjacent part of the frame. The hopper 77 stands at a downk ward and inward angle of inclination so that the bolts placed therein may he caused to gradually and regularly fall into the slot 7H with thc heads of the bolts uppermost. 'l`he ledges HU at the inner outlet eml 79 of the hopper stand over and slidingly bear upon the outer ends of parallel rails 86 which are inclined upwardly at their outer extremities and merge into horizontal incinin the form of bers 87, which ('ontinut` around in rota-ontrh' relation to the bolt frudvr and plawr 2&5 and thon change curvo and prot-t't owl' thil bolt` fetedvr and planar bt-low. as at SS. ser Fig. 2. for tht` purpost` ot dist'harging tht nutted bolt'a4 downwardly and through tho bastl or frame.
